ABSTRACT:
The present invention provides a basic slag for use to protect molten steel in a tundish during continuous casting processes. The preferred slag of the present invention comprises a combination of CaO, MgO, Al.sub.2 O.sub.3, and TiO.sub.2. The resulting tundish covering has exceptional insulation, protective and Al.sub.2 O.sub.3 absorptive properties, while avoiding operational problems encountered with previous basic tundish slags, such as crusting and refractory erosion.
